Photoshop Document
The industry standard for digital image editing.
PSD (Photoshop Document) is the proprietary file format of Adobe Photoshop. It is the de facto standard in the digital art, photography, and graphic design industries. Unlike final output formats (JPG, PNG), a PSD is a working file that preserves the editor's state: independent layers, editable text, masks, blend modes, filters, and paths.
A PSD file is divided into five major parts: File Header, Color Mode Data, Image Resources (metadata like paths, guides), Layer and Mask Information (the bulk of the data), and Image Data (a flattened backward-compatible preview). This structure allows Photoshop to save complex non-destructive editing states.
Created by Thomas Knoll in 1988 for the original version of Photoshop. It has evolved with every version of the software, adding support for new features (vectors in v6, smart objects in CS2) while maintaining remarkable backward compatibility.
Portable Any Map
A super-class extension for the PBM, PGM, and PPM formats.
PNM (Portable Any Map) is not a distinct file format itself but rather a collective name (and file extension) used to handle files that could be any of the specialized Netpbm formats: PBM (Bitmap), PGM (Graymap), or PPM (Pixmap). A file ending in `.pnm` allows a program to implement a single reader that automatically detects the internal format ('P1' through 'P6') and handles it accordingly.
A `.pnm` file is simply a PBM, PGM, or PPM file renamed. The header magic number (e.g., `P6`) determines the actual content. This abstraction simplifies command-line pipelines, allowing users to pipe `image.pnm` without worrying if the image is black-and-white or full color.
Part of the Netpbm project philosophy to create a unified library for handling raster graphics. It simplifies naming conventions for software that can output any of the subtypes.
